General Description
The Supertex HV853DB1 demoboard contains all the
necessary circuitry to demonstrate the features of the HV853
EL lamp driver. The HV853 is the low noise version of the EL
driver HV852 with improved EMI performance.
Simply connect it to a power supply and a lamp as shown in
Figure 1. For additional assistance with the HV853 demoboard
circuit, please refer to the HV853 datasheet.
Board Layout and Connection Diagram
Connections:
V
Supplies the HV853 EL driver IC. The supplied demoboard
is optimized for 3.2 to 5.0V operation.
EN (Enable Input)
A logic input which enables/disables the driver. Connect EN
to logic high (V
to disable the driver. This input may be connected to a me-
chanical switch or to a logic circuit output.
CLK
A logic input pin to which an external clock can be applied
to set the EL lamp frequency. CLK
